Yuav ua li cas kom txo hwj huam mov mov ripple?
1.Energy cia inductance.Qhov nqi qis hauv kev khiav hauj lwm zaus ntawm lub zog sotrage inductance, qhov loj dua qhov zoo dua, tab sis ntau tus neeg tsuas them nyiaj rau cov nqi ntawm inductance, qhov tseeb, cov kev cuam tshuam ntawm Q nqi ntau dua, ntev li ntev tau npaum li cas ntawm cov kev txwv ntawm kev ua kom muaj kev sib tham, raug tso cai rau hloov mus ua ntau yam.
2.Filter capacitor.ESR thiab ESL ntawm lim capacitor yog ob qho tsis tseem ceeb, qhov qis zoo, tsuas mus caum peev yog deb ntawm txaus.Thaum kawg, tom qab ntsib ESR thiab ESL, loj peev yog zoo dua.Filter ntawm switching fais fab mov yog nyiam dua X7R los yog X5R capacitors thiab tantalum electrolytic, thiab lub ripple yog me ntsis relaxed nrog ib tug Y5V capacitor thiab nyias, siab-zoo aluminium electrolytic (tsawg ESL).
3. PCB tsim. Switching power supply PCB tsim yog ib qho tseem ceeb heev. Yog tias thawj ob yam kev ua tau ntsib, tab sis ripple tsis tsawg tshaj li tus nqi teev nyob rau hauv phau ntawv, qhov teeb meem yuav yeej tawm ntawm PCB.Switching fais fab mov nti piv txwv thiab lim circuit tsim yog heev xyov cov PCB faib tsis yuav ua rau kev hloov kho yuam kev lossis kev ua haujlwm tsis zoo nkauj, txawm yuav ua rau nws tus kheej-zoo siab (feem ntau hauv ib qhov kev siv khomob tshwm sim), nws yuav tsum tau saib xyuas.Qhov ntsiab lus yog qhov sampling voj thiab lim circuit sim mus kaw mus rau lub hwj huam hloov IC, PCB cov cwj pwm tsis tuaj yeem ua ntev heev, dhau lawm nyias, zoo ib yam li lub zog cia kev qis, tab sis feem ntau yog me ntsis me me, layout, sib ncag yog sib npaug txo qhov inductance ntawm tus nqi q.Thenzhen ECON Technology Co , .Ltd muaj hluav taws xob muaj kev pabcuam R & D, yog li peb tuaj yeem kov tau PCB tsim txig.
Thaum kawg, thaum lub hwj huam switching IC internal Circuit Court tsim ntau ua rau nyias cov cim ntsuas sib txawv, feem ntau, qhov siab hloov zaus yog ib qho yooj yim kom tau txais qis dua, tab sis tus nqi thiab cov kev cai ntawm lwm cov khoom sab nraud ntau, Yog li raws li rau qhov kev xav tau rau ib qho kev xaiv tsim nyog, txaus rau qhov yuav tsum tau yog ok, los yog them cov nqi tsis tsim nyog.Nws yog qhov yuav tsum tau nyeem phau ntawv thiab to taub ua ntej tsim lub hwj chim. steppers.
